Abstract: A method for producing a microelectronic structure is suggested in which a layer structure (30) which partially covers a substrate (5) and which comprises at least one first conductive layer (15,20) which reaches to a side wall (35) of the layer structure (30), is covered with a second conductive layer (45). The second conductive layer (45) is then subsequently back-etched to as great an extent as possible with an etching process with physical delamination, wherein delaminated material deposits on the side wall (35) of the layer structure (30). On the side wall (35) the delaminated material forms a protection layer (60) by means of which the first conductive layer (15,20) is to be protected from attack by oxygen to the furthest extent possible.

Abstract: A bipolar transistor comprising a collector region of a first conduction type, and a subcollector region of the first conduction type at a first side of the collector region. The transistor further includes a base region of the second conduction type provided at a second side of the collector region, and an emitter region of the first conduction type which is provided above the base region on the side remote from the collection region. A carbon-doped semiconductor region is provided on the first side alongside the collector region. The bipolar transistor is characterized in that the carbon-doped semiconductor region has a carbon concentration of 1019-1021 cm−3 and the base region has a smaller cross section than the collector region and the collector region has, in the overlap region with the base region, a region having an increased doping compared with the remaining region. The carbon-doped semiconductor region prevents an outdiffusion from the zone of the collector region into the remaining region of the collector region.

Abstract: A bipolar transistor includes a first layer with a collector. A second layer has a base cutout for a base. A third layer includes a lead for the base. The third layer is formed with an emitter cutout for an emitter. An undercut is formed in the second layer adjoining the base cutout. The base is at least partially located in the undercut. In order to obtain a low transition resistance between the lead and the base, an intermediate layer is provided between the first and the second layer. The intermediate layer is selectively etchable with respect to the second layer. At least in the region of the undercut between the lead and the base, a base connection zone is provided that can be adjusted independent of other production conditions. The intermediate layer is removed in a contact region with the base.

Abstract: In producing a silicon capacitor, hole structures (2) are created in a silicon substrate (1), at the surface of which structures a conductive zone (3) is created by doping and whose surface is provided with a dielectric layer (4) and a conductive layer (5), without filling the hole structures (2). To compensate mechanical strains upon the silicon substrate (1) which are effected by the doping of the conductive zone (3), a conformal auxiliary layer (6) is formed on the surface of the conductive layer (5), which auxiliary layer is under a compressive mechanical stress.

Abstract: Significant amounts of pattern distortion were found to be the result of reflowing borophosphosilicate glass (BPSG) and silicon dioxide shrinkage during high temperature junction anneals. In order to remedy this problem, a method for suppressing the pattern distortion by subjecting the wafer coated with BPSG and with silicon dioxide layers to a high temperature anneal before patterning is disclosed. The high temperature anneal densifies the undoped silicon dioxide before patterning, so that shrinkage of the undoped silicon dioxide does not affect the patterning steps.

Abstract: A method for making an electrical connection between a trench storage capacitor and an access transistor in a DRAM cell. The electrical connection is formed through the selectively controlled outdiffusion of either N-type or P-type dopants present in the trench through a single crystalline semiconducting material which is grown by epitaxy (epi) from the trench sidewall. This epitaxially grown single crystalline layer acts as a barrier to excessive dopant outdiffusion which can occur in the processing of conventional DRAMs.

Abstract: Rod-shaped or cylindrical structures in the nm range on a substrate of silicon are manufactured. A first cylinder of silicon is selectively epitaxially deposited in the hole of a mask layer of oxide, and the mask layer is removed. The silicon is then oxidized to form an oxide layer having such a thickness that a thinner, second cylinder of silicon having practically the same height as the first cylinder remains. In a last step, this oxide layer is removed, so that the second cylinder forms a freestanding silicon rod on the surface of the substrate.

Abstract: For producing a laterally limited, single-crystal region on a substrate, for example the collector of a bipolar transistor or the active region of a MOS transistor, a mask layer having an opening is produced on the surface of a substrate. The surface of the substrate is exposed within the opening. The cross-section of the opening parallel to the surface of the substrate at the surface of the substrate projects laterally beyond that cross-section at the surface of the mask layer. The sidewall of the opening proceeds essentially perpendicularly relative to the surface of the substrate in the region of the surface of the mask layer and has a step-shaped profile in cross-section perpendicularly relative to the surface of the substrate. The single-crystal region is formed by selective epitaxy within the opening.

Abstract: A turn-off thyristor whereby an n-base layer not contacted by a gate electrode has at least one thin semiconductor layer inserted into it that is oppositely doped. Its distance from a pn-junction between a p-base and the n-base is selected so small that the maximum field strength of the space charge zone building up at this pn-junction upon turn-off of the thyristor is limited to a non-critical value at which an avalanche breakdown with respect to the charge carriers to be cleared out does not yet occur.
